The dipyridine (dipy) complexes of rare earth(Ⅲ)B₂₀H₁₈ were prepared throughfollowing reactions: 3H₂B₂₀H₁₈+Ln₂O₃→Ln₂(B₂₀H₁₈)₃+3H₂O, Ln₂(B₂₀H₁₈)₃+8dipy[Ln(dipy)₄]₂(B₂₀H₁₈)₃ where Ln=Yb, Tm, Ho, Gd and Sm.All the compounds obtained are solid and soluble in polar solvents, but not in nonpolar solvents. They are stable to air and moisture.The complexes were identified by elemental analysis, electroconductivity, IR spectra and TG-DTA measurements. Dipy is found to be Londed to the rare earth via N atom.The molar conductance data indicate that these complexes are ionic and behave as 2:3 electrolytes in DMF.
